Oracle Cloud Infrastructure 2025 DevOps Professional Sample Questions (Q11-Q16):

NEW QUESTION # 11
Which two are prerequisites for creating a secret in Oracle Cloud Infrastructure Vault service? (Choose two.)

A. You must have an auth token to encrypt the secret.
B. You must have the required permissions to create and manage secrets in the Vault service.
C. You must have a Vault managed key to encrypt the secret.
D. You must first create a hash digest of the secret value.
E. The user must create a compute instance to run the secret service.

Answer: B,C

Explanation:
You need the required permissions (such as policies allowing secret management) to create and manage secrets in Oracle Cloud Infrastructure (OCI) Vault service. These permissions are essential for performing operations such as creating, reading, and managing secrets.
Vault managed key is required to encrypt the secret before it is stored in the OCI Vault. The managed key acts as the encryption key for securing the secret, ensuring its confidentiality.

NEW QUESTION # 12
As a DevOps engineer working on containerizing a microservices-based application to be hosted on OCI Cloud platforms, which step can help ensure that the container images have not been modified after being pushed to Oracle Cloud Infrastructure Registry (OCIR)?

A. Signing the image using the Container Registry CLI and creating an image signature that associates the image with the master encryption key and key version in the Vault service
B. Scanning the image upon ingestion and comparing the image size for changes
C. Deploying a manifest to the Kubernetes cluster that references the container image and its unique hash
D. Enabling scanning of container images stored in OCI Registry

Answer: A

Explanation:
To ensure that container images have not been modified after being pushed to the Oracle Cloud Infrastructure Registry (OCIR), you should sign the image. This involves using the Container Registry CLI to create a digital signature for the image, which associates the image with a master encryption key and key version stored in the OCI Vault service. This signature can then be verified at the time of deployment, ensuring that the image has not been tampered with since it was signed.

NEW QUESTION # 13
As a developer working on a software project to be deployed on OKE, you have created a Helm chart for your application. You want to deploy the chart using OCI DevOps service.
Which statement is true about deploying a Helm Chart using OCI DevOps service?

A. The Helm charts must be located in the OCI Container Registry repository for deployment.
B. Oracle Cloud Infrastructure (OCI) DevOps service supports deployment of Helm charts to Container Instances.
C. A single chart can be installed only once into the same cluster, and create single release.
D. The values.yaml file is a generic file located in the OCI Container Registry. You must create a reference to this file.

Answer: A

Explanation:
OCI DevOps service can be used to deploy Helm charts for Kubernetes-based applications running on Oracle Kubernetes Engine (OKE). For deploying the Helm chart through the OCI DevOps service, the Helm chart must be stored in the OCI Container Registry. This allows the OCI DevOps service to easily access the Helm chart during the deployment process.

NEW QUESTION # 14
The Kubernetes Master node serves as the central control plane for managing the cluster's resources and orchestrating workload deployment.
What are the primary responsibilities of the Kubernetes Master node?

A. The Master node is primarily tasked with executing application workloads and ensuring their availability within the cluster.
B. The Master node serves as a repository for storing container images, facilitating rapid deployment and scaling of applications.
C. The Master node oversees the scheduling and allocation of cluster resources, ensuring optimal utilization across nodes.
D. The Master node monitors network traffic within the cluster, ensuring secure communication and efficient data transfer between nodes.

Answer: C

Explanation:
The Kubernetes Master node is the central control plane responsible for managing the cluster's resources and orchestrating workload deployment. Its primary responsibilities include:
Scheduling: Deciding which workloads (pods) should run on which worker nodes, based on resource availability and scheduling constraints.
Resource Allocation: Allocating resources to workloads to ensure optimal utilization across nodes.
Cluster Management: Maintaining the desired state of applications, managing cluster events, and ensuring that all the components of the cluster are functioning properly.

NEW QUESTION # 15
Observability helps understand system behavior, but it has limitations.
Which of the following tasks cannot be accomplished solely through observability?

A. Automating software deployments
B. Identifying resource consumption
C. Optimizing resource utilization
D. Identifying infrastructure bottlenecks

Answer: A

Explanation:
Observability refers to the ability to understand a system's internal state by observing its outputs. It involves metrics, logs, and tracing to provide insights into the system's behavior, which helps in monitoring and identifying issues.
